Sea-ice response to climate change in the Bering Sea during the Mid-Pleistocene Transition

, 2021
Sea-ice is believed to be an important control on climatic changes through the Mid-Pleistocene Transition (MPT; 0.6–1.2 Ma). However, the low resolution/short timescale of existing reconstructions prevents a full evaluation of these dynamics.

Halogen-based reconstruction of Russian Arctic sea ice area from the Akademii Nauk ice core (Severnaya Zemlya) [PDF]

The Cryosphere, 2016
The role of sea ice in the Earth climate system is still under debate, although it is known to influence albedo, ocean circulation, and atmosphere–ocean heat and gas exchange.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Experiments on sea ice fracture toughness in the Bohai Sea

Shui kexue jinzhan, 2013
The fracture toughness of sea ice is an important parameter to analyze ice load on offshore structures,and also affects the sea ice dynamics,such as sea ice breakage,rafting and ridging,etc.In this study,sea ice samples were collected in the Liaodong Bay

Pancake sea ice kinematics and dynamics using shipboard stereo video

Annals of Glaciology, 2020
In the marginal ice zone, surface waves drive motion of sea ice floes. The motion of floes relative to each other can cause periodic collisions, and drives the formation of pancake sea ice.

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

A study on the role of sea ice in the nitrous oxide cycle in the Prydz Bay, Antarctica

Frontiers in Marine Science
N2O is one of the most important greenhouse gases and ozone depletor, which was a matter of more and more concerned. The Southern Ocean was considered as one of the most important N2O source and was believed to account for ~1/4 of oceanic budget. However,

Ice dynamics in the central Greenland Sea [PDF]

Journal of Geophysical Research: Oceans, 2006
Until recently a tongue‐shaped sea ice feature formed over the central Greenland Sea each winter. This tongue, known to generations of Norwegian sealers as “Odden,” sometimes protrudes several hundred kilometres in a northeast direction from the main East Greenland ice edge. Owing to the high wave energy in the Greenland Sea in winter, the formation of

An assessment of key model parametric uncertainties in projections of Greenland Ice Sheet behavior [PDF]

, 2012
Lack of knowledge about the values of ice sheet model input parameters introduces substantial uncertainty into projections of Greenland Ice Sheet contributions to future sea level rise.

A role for eIF5A in translational control of stress‐inducible proteins in multiple myeloma cell lines

Molecular Oncology, EarlyView.
Loss of eIF5A rewires thapsigargin‐mediated endoplasmic reticulum stress responses in multiple myeloma cells by selective translation of mRNA transcripts, consequently dampening thapsigargin‐induced unfolded protein response (UPR) activation and shifting the balance from induction of apoptosis toward cell survival and proliferation.
